Best ways to prolong the service life of the submersible pump

In urban construction, the excavation of foundation, auxiliary underground pipelines, bear the brunt of the underground water is the problem to be solved, and the key to solve the problem is to use the water pump can be successfully take out from underground water and sludge, the general water submersible pump will not be able to complete the project, because of the subgrade under water with a lot of sediment, it will pump impeller pump motor burn out, jam and so it must use the submersible sewage pump to complete the task of pumping.

On the popular diving sewage pump in use on the market at present is to make a lot of convenient for city building construction units, but it also has some disadvantages, which is the service life is not too long, the reason is because the sludge with different specifications of the garbage and stone, in the form of the pump body outlet blockage or entangled impeller make motor does not turn, the above situation happened pump can no longer use it soon.

To solve this problem must be water pump suction clutter and long fiber after cutting emissions, then the dirty sand and water play out, such not only prolong the service life of the pump, more create conditions to speed up the construction of municipal engineering. There is a stir type electric pump, its role and cutting is slightly different. It is equipped with all agencies attachments, when pumping water to the bottom, because of the underwater sediment or sediment reaches a certain concentration ratio and uneven, and the water drain is thick sediment not sucked into jam, it first need to put them to form a uniform thin and diluted to sediment, it is not easy to damage electric pump type. In addition to keep the main impeller shaft to the force balance, must set up a deputy impeller structure, it can reduce the pressure of the sealed cavity, make electric pump axial force and the service life of mechanical seal are greatly improved. For the heat dissipation problem of electric pump is always the key problems of the service life of the electric pump, if the cooling effect is not good, the motor temperature will rise, make the power of the motor continuously litre, easy to motor burn out, shorten the service life of the pump.

In order to solve this problem, we adopt circulating cooling system, to strengthen the function of heat dissipation, it can ensure that when the pumps above the water, also can work normally. Serious corrosion for lining liquid, can use first stainless electric pump, its resistance to corrosion, and the use of reliability will be greatly improved.
